Résumé du poste

GLOBALFOUNDRIES Singapore is seeking a Lithography Process Engineer to sustain, optimize and develop photolithography processes in a high-volume fabrication environment. You will work with advanced lithography tools to ensure CD control, overlay accuracy, and defect reduction.

You will monitor SPC charts, perform CD/overlay analyses, and drive process improvements across exposure tools, resist processing, and metrology.

Qualifications

• Bachelor degree in Electrical/Electronics/Mechanical/Mechatronics/Microelectronics Engineering.
• 1 to 3 years of semiconductor wafer process engineering experience.
• Ability to identify, assess and solve problems.
• Willingness to perform normal or 12-hour rotating shifts.

Responsabilités

• Monitor SPC/ESPC charts for lithography modules using SPACE and respond to OOC/OOS events.
• Perform CD/overlay analysis using CD-SEM, scatterometry, and overlay metrology tools.
• Optimize photoresist coating, soft bake, exposure, PEB, and development processes.
• Tune stepper/scanner tools (ASML/Nikon) for optimal performance and matching.
• Conduct DOE and split-lot analysis using JMP and related tools.
• Troubleshoot lithography defects such as bridging, footing, scumming, and residues.
• Collaborate with Equipment Engineers on FEM and process window optimization.
• Maintain reticle management, focus/exposure control and alignment strategies.
• Drive CD uniformity, overlay performance, LER, and CDU improvements.
• Support technology transfers, NPI, and process ramp-up activities.
• Lead cross-functional teams to resolve yield excursions and implement CAPA.
• Ensure compliance with TS16949 and audit/documentation requirements.
